/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 59423.012976 0.000434 0.24538 0.03878 0.98000 0 3.27983 0.23150 2.76684 0.19527 0.80480 0.11382 0.68141 0.09637 59423.013977 0.000567 0.18075 0.02792 0.97959 0 3.42150 0.21239 2.89148 0.17948 0.61842 0.08746 0.52170 0.07378 59423.015053 0.000509 0.18810 0.02956 0.98864 0 3.59756 0.23014 3.02525 0.19354 0.67669 0.09714 0.56801 0.08153 59423.016072 0.000509 0.18753 0.02891 0.95455 0 3.78149 0.23175 3.16948 0.19423 0.70915 0.10030 0.59623 0.08432 59423.017029 0.000448 0.18148 0.02856 0.98065 0 4.24448 0.26696 3.55248 0.22342 0.77029 0.11111 0.64730 0.09338 59423.017868 0.000391 0.22962 0.03632 0.97778 0 3.96516 0.27513 3.29587 0.22868 0.91050 0.12941 0.75547 0.10737 59423.018774 0.000515 0.19622 0.03063 0.92697 0 3.68555 0.23207 3.07136 0.19338 0.72317 0.10328 0.60169 0.08594 59423.019790 0.000501 0.18849 0.02940 0.97688 0 3.74723 0.23455 3.11377 0.19488 0.70632 0.10089 0.58744 0.08390 59423.020802 0.000512 0.19670 0.03031 0.97740 0 3.57842 0.22482 2.98978 0.18784 0.70386 0.09905 0.58801 0.08274 59423.022105 0.000790 0.18671 0.02271 0.97070 0 3.90876 0.19029 3.27268 0.15930 0.72981 0.08135 0.61066 0.06806
